This visualization presents the Auto MPG dataset from the UCI Machine Learning Repository, plotting vehicle weight against horsepower while encoding origin via color and mpg through circle size. The code uses the Vega-Lite API to declaratively construct the scatter plot, registering Vega, Vega-Lite, and Vega-Tooltip for rendering and interactivity. D3’s `csv` function loads the remote data, while custom configuration adjusts axis styles and font sizes. The visualization fills the window, with tooltips displaying vehicle origin on hover.
